Much to the relief of the DX community, the ARRL retracted its recent deletions of KH4, Midway Island, and KH7K, Kure Island, from the active list of DXCC entities.  Those deletions caused a major “disturbance in The [DX] Force”, especially for those DXers who had recently qualified for Honor Roll status or who had recently achieved a new milestone in the DX Challenge standings.  What DXers found most disturbing about the deletions was that they were ordered by ARRL Headquarters without any consultation with the DX Advisory Committee (DXAC).  This was a big topic of conversation at the 2017 International DX Convention in Visalia, California in April.

Radio conditions for DXing continue to be challenging during the bottom of the sunspot cycle.  This time of year the only bands showing any promise for working DX are from 17 meters to 40 meters and many days even those bands are limited to domestic propagation only.  We are in the Sporadic E season, however, and that means 6 meters may provide some surprises with multiple-hop signals reaching beyond our borders.  It is a good time to keep the N3TUQ “6 Meter DX Map” open on a computer screen to watch for openings.  https://n3tuq.com/dxmap.php

Field Day is rapidly approaching.  It is an event I have enjoyed throughout my ham radio career.  While CADXA does not have its own FD activity, there are plenty of general interest radio clubs looking for operators.  I am hoping to get up north for a "cool weekend" and enjoy FD in the pine trees.

June Meeting

Announced DX Operations
by NG3K

We had over 70 people attend the May Barbecue Meeting.  Thankfully, the PERA Club allowed us to move this annual event indoors once we saw the forecast high temperature of 104 degrees.  Last year we survived gale force winds and moved indoors for the presentation after eating windblown BBQ food in the ramada.  This year, we did it all indoors rather than risking heat stroke and dehydration. 

The program by Ned, AA7A, on his life in ham radio moonbounce was very well received.  He took us through the fascinating journey of moonbounce technology from its birth as a concept in World War 2 up to the present day in Maricopa, AZ where he and others are constructing what will be one of the largest moonbounce antennas in the world at a site owned by Larry, WO7R.

I know there are many of us who would like to experience this most unique mode of ham radio and at least hear our signal's  echo after it bounces off the moon.


May Meeting Recap

Central Arizona DX Association

We are the largest ham radio DX club in Arizona with over 120 members, many of whom are on the ARRL's DXCC Honor Roll.  We have several members who have traveled to distant places to put "rare" countries on the air.  We encourage any ham interested in DXing to join our club and learn about the many aspects of talking to hams around the globe who share this amazing hobby with us.  Founded in 1974, we are an ARRL-affiliated club and a member club of the Amateur Radio Council of Arizona (ARCA).

Our next meeting will be on Thursday night, June 1st, at the PERA Club beginning at 7:00 pm.  The program will be “The High Frequency Active Auroral Research Program (HAARP) - An Engineer's View” presented by Steve Floyd, W4YHD, Chief Design Engineer for the HAARP facility in Alaska.  Steve will provide a detailed summary of the design, construction, and operation of this state-of-the-art radio science facility.  HAARP is the highest power HF transmitting system in the world with 180 20 KW each multi-mode radio transmitters, and has recently returned to operation under new ownership of the University of Alaska.

Please feel free to arrive early to socialize with your peers.  Refreshments will be served at the break.  Guests are always welcome.
